2) CN1B
Signal Name Symbol Pin No. Description I/O Division
I/F Internal power
supply
VDD 3 Used to output 24V 10% to across VDD-COM.
When using this power supply for digital interface, connect it with
COM.
Permissible current: 80mA
Digital I/F power supply
input
COM 13 Used to input 24VDC 10% for input interface.
Driver power input terminal for digital interface.
COM of each connector is connected in the servo amplifier.
When using an external power supply, connect a power supply of
24VDC, 200mA or more to this terminal.
Digital I/F Common SG 10, 20 24VDC common terminal for VDD, COM, etc. and isolated from LG.
Servo on SON 15 When SON-SG are connected, the base circuit is switched on and the
servo amplifier is ready to operate.
When they are disconnected, the base circuit is shut off and the servo
motor coasts.
DI-1
Synchronous operation
start
STS 14 To start synchronous operation, connect STS-SG. DI-1
Forward rotation start ST1 8 Forward rotation start signal input terminal.
In automatic operation mode, the servo motor rotates in the advance
rotation direction as soon as ST1-SG are connected.
In JOG operation mode, the servo motor rotates in the forward rotation
direction while ST1-SG are connected.
DI-1
Reverse rotation start ST2 9 Reverse rotation start signal input terminal.
In automatic operation mode, the servo motor rotates in the retard rotation
direction as soon as ST2-SG are connected.
In JOG operation mode, the servo motor rotates in the reverse rotation
direction while ST2-SG are connected.
DI-1
Point block No. selection DI1 17
Point table No. selection signal input terminal.
The following table lists the point blcok numbers which may be chosen by
the DI1:
DI1 Selected Point Table #
0 Point block No.1
1 Point block No.3
Note: 0: DI1-SG open
1: DI1-SG connected
DI0 is connected in parameter No.86 as the factory default.
DI-1
Automatic/manual
selection
MOD 7
Short MDO-SG to choose the automatic operation mode, or open them
to choose the manual operation mode.
DI-1
Trouble ALM 18 ALM-SG are disconnected when the protective circuit is activated to
shut off the base circuit at power off.
They are connected in normal condition at power off.
DO-1
Synchronous completion SYC 19 SYC-SG are connected when the motor speed reaches at a synchronous
speed.
DO-1
Overlap completion SYF 6 SYF-SG are connected when the motor speed reached advanced / retard
speed after ST1-SG or ST2-SG are connected
